Adjuvant Radiotherapy on Circulating Cells in Breast Cancer Patients

Radiation applied to the preserved breast during radiotherapy treatment activates numerous molecular cascades in tumor bed adjacent cells causing an inflammatory state. During this process, pre-clinical studies demonstrated CD11b + and CD11b+cKit+cells mobilization in the blood. These cells are involved in numerous processes during tumor progression/control and metastases development. The expected results in clinical setting allow us to investigate the development of innovative therapeutic and monitoring strategies. The clinical repercussions would consist in identifying new predictive and prognostic targets in breast cancer.
